 What is The Co-Axial Rotor Blades RC Helicopters ?

An RC helicopter using a contra-rotating system will have two rotors spinning in opposite directions. The torque generated by the rotor blades is canceled out, and the rc helicopter will not require a tail rotor to keep it from spinning. This allows the rc helicopter's tail boom to be eliminated, saving weight. One possible layout has one rotor blade mounted at each end of a long fuselage, as it is for the Boeing CH-47 Chinook, and is known as a tandem rotor. Alternatively, both contra-rotating rotors can be placed on the same shaft, resulting in a co-axial design. Co-axial rc helicopters are very stable and easy to fly. The Bladerunner series indoor rc helicopters use co-axial designed rotor blades.
